Risoba
guichardi
sp. n.
14mm, 
15mm. The facies is of the repugnans type. The forewing is a very dark
green, with basal and apical patches as in the repugnans group. However
the former is relatively large (the thorax being a similar pale creamy fawn
colour) and the latter relatively small, lacking the arcuate division seen in
other species. There is only a single, rather elongate patch more distally on
the dorsum. There is a dull ochreous fawn discal spot. The male genitalia have
rather short valves, but these are ornamented weakly as in the repugnans
group. The aedeagus vesica has two spined bands rather than separated large
cornuti.
